Key Features & Performance

Defoamer for Solvent-Based Coatings

★ Powerful & Persistent Defoaming

LD-2530 industrial defoamer rapidly breaks existing foam and inhibits its formation during high-shear mixing and application. Its high performance ensures a bubble-free film, preventing pinholes and craters in the final coating.

★ Excellent Compatibility & No Surface Defects

Specifically designed for epoxy and other resin systems, silica defoamers offer outstanding compatibility without causing cloudiness, fish eyes, or orange peel. This ensures high clarity and a flawless surface finish.

Defoamer for Industrial Coatings

★ Effective in Solvent-Free Systems

Unlike many conventional defoaming additives, LD-2530 paint defoamer performs exceptionally well in solvent-free and high-solid formulations. It maintains its efficacy even in challenging environments, making it versatile for modern eco-friendly coatings.

★ Optimized for Production Efficiency

Its unique chemistry allows for easy incorporation at any stage of the manufacturing process. It helps reduce production time by quickly eliminating entrained air, leading to higher throughput and consistent quality.

FAQ

Q1 What is LD-2530 Defoamer?
LD-2530 is a high-performance air release additive and a solution of foam destroying polymers and polysiloxanes. It is designed to prevent and eliminate foam in solvent-based and solvent-free coatings, adhesives, and sealants, and is particularly effective in epoxy resin systems.
Q2 What is the recommended dosage for LD-2530 defoamer?
The typical addition level is between 0.1% and 0.7% of the total formulation weight, depending on the resin system and foaming tendency. For epoxy systems, the optimal dosage is usually found within this range and should be determined through a ladder test.
Q3 How should LD-2530 defoaming additive be stored?
Store LD-2530 deoaming additive in a cool, dry, and well-ventilated area away from direct sunlight and sources of ignition. Keep containers tightly sealed when not in use. Under recommended storage conditions, the shelf life is 2 years from the date of production.
Q4 Is LD-2530 silica defoamer compatible with clear coatings?
Yes, LD-2530 silica defoamer is formulated for excellent compatibility and will not cause haze or cloudiness in clear coatings when used at recommended dosages. It is designed to provide effective defoaming without compromising the optical clarity of the final film.
Q5 Can LD-2530 silicone based defoamers be used in two-component epoxy systems?
Absolutely. LD-2530 silicone based defoamer is especially recommended for epoxy resin systems. It can be added to either the base resin or the hardener component, provided compatibility is checked. Its stability ensures reliable foam control throughout the pot life and application of the mixed system.
Q6 What packaging options are available for silicone defoaming agent?
Defoaming agent additive is typically supplied in 25kg and 200kg iron drums to suit different customer needs. Please contact us for specific packaging requirements or custom orders.
